How many FLOPS does the average computer run at?
This varies wildly from processor to processor, and dependant on the actual amount of the computer you're measuring!
CPUs are very complex, and as such, they tend to execute highly specified, complex 32-bit or 64-bit code (and some 128-bit special operations) at a rather slow pace. They're very powerful, due to multithreading and multitasking capabilities. But their overall raw firepower is relatively low.
The average Intel Core i750 can push 7 GFlops maximum without overclocking. The Intel Core2Quad 6.9 GFlops. The AMD Phenom II X4 can push 7.5 GFlops.
Phenom II X3 can push 4.5 GFlops.
Phenom II X2 at 3.3 GFlops. Core2Dup E8200 at 2.9 GFlops.
Celeron M 540 at 0.9 GFlops and Pentium4 at 0.74 GFlops.
(Results from MaxxPi^2)
However other components, such as the GPU, can be much faster. This is because their calculations are simpler and require less degree of accuracy and floating point precision.
An nVidia GeForce 8800GS can pull 264 GFlops, and a GeForce 9800GT clocks in at 336 GFlops.
(Any cards before the 8k series did not have 32-bit floating point precision and thus couldn't be measured in flops)
An ATI HD 2400 series is 56 GFlops. 3400 series is 64 GFlops. A 3690 is 428.8 GFlops and 3870 is 496 GFlops. 4890 is 1360 GFLops (1.36 TFlops)
(Cards before the HD 2400 series didn't have floating point precision, except the 9800 series which sorta did.. kinda)
However, FlOPs are not the best measurement of true speed, only raw execution rate. Actual processor speed is dependant on many other factors such as response time, number of pipelines, pipeline length, cache size, cache latency, cache associativity, instruction sets, register size, number of registers, and more. And as such, Flops should NOT be used as a measurement of CPU performance except when comparing two similar processors (such as identical architecture, like AMD vs. Intel x86 with equal cores)
Ultimately, in CPUs alone, it can range from 0.25 GFlops to 7.5 GFlops in the average consumer computer, and up to 20 GFlops for x86 servers [12-core].
GPUs can vary to as much as 2.5 TFlops or more, and changing weekly, or as little as 10 GFlops.
Total, you can expect a PC, all in all, to be capable of 2 to 2600 GFlops in a modern computer, based on hardware configuration. [Ultra-efficiency systems like 533 MHz VIA systems with onboard Unichrome graphics would get maybe 2 GFlops tops, due to their ultra-low power design)
The hardware component that does all the calulations and processing is known as the processor or.?
Central Processing Unit(CPU)
What are the scheduling criteria for CPU scheduling?
CPU Scheduling Criteria:
There are many scheduling algorithms and various criteria to judge their performance. Different algorithms may favor different types of processes. Some criteria are. as follows:
• CPU utilization: CPU must be as busy as possible in performing different tasks. CPU utilization is more important in real-time system and multi-programmed systems.
• Throughput: The number of processes executed in a specified time period is called throughput. The throughput increases .for short processes. It decreases if the size of processes is huge.
• Turnaround Time: The amount of time that is needed to execute a process is called turnaround time. It is the actual job time plus the waiting time.
• Waiting Time: The amount of time the process has waited is called waiting time. It is the turnaround time minus actual job time.
• Response Time: The amount of time between a request is Submitted and the first response is produced is called response time.
A CPU scheduling algorithm should try to maximize the following:
• CPU utilization
• Throughput
A CPU scheduling algorithm should try to minimize the following:
• Turnaround time
• Waiting time
• Response time

Specific or static?
Each computer has an address, most of the time a TCP/IP address in a pattern of four sets of three numbers.
There's also MAC address, which is a pattern of 8 sets of 2 digits, which are assigned to every network adapter.
What are the parts of a usb cable?
A USB Cable can have multiple types of plug ends which are called connectors (Standard-A, Standard-B, Mini-B, Micro-A, Micro-B, and Micro-AB).
Obviously there are wires between the two connectors and they are:
One wire contains a path for a 5V power supply
Two wires are twisted-pair data wires
One wire is the ground
The basic data and instructions used to start the computer are called?
It's a mixture of things. BIOS, CMOS, Operating system.
How long should a 2wire modem last?
A good general rule is that any electronic is only *designed* to last for the duration of it's warranty, and not much longer.
My two 2wires lasted 2, and 3+ years respectively. The first had to be replaced because Qwest upgraded their DSL, making it incompatible.
Is there any software to detect a output for an electric motor by giving an input?
Just a suggestion... try looking for a software programmer, Java programmer to help you. They can create program for your problem in your electric motor. but it will cost you some dollars. as long as you are willing to pay, computer programmers can help you.
Try looking for software programmers online, there's a lot of them. ok?
Hoped my suggestion helps you.
How much does a USB port cost?
For manufacturers, the cost to implement them on a motherboard is only a couple of cents. If you want to add a USB hub to your computer, they can usually be had for under $20.
Will a Conexant RS232 V92 Modem answer a distinctive ring?
yes it will. More can be found in the data sheet at Conexant's web site
Where is a AOSS button on a telus router?
The Telus Routers do not have an AOSS button. I believe only Buffalo Routers have one.
Is there software that allows you to control a usb device you made?
If you have the skills to create your own USB device, you should have the skills necessary to write a device driver for it.
What Hardware devices that allow the computer to accept the data for processing?
this question is obscure. you may want to re-phrase it. If you are talking of input devices, then:
- keyboard
- mouse
- microphone
- webcam
- graphics tablet
put it in a different computer and see if it works. (easiest way)
What is the location of the NIC chip in your computer?
The "network interface card" in your computer could be in a number of locations, I would need more specifics (motherboard, year, manufacture) in order to exactly tell you. But you can look at the motherboard and find out yourself.
Where you plug your network cable into (RJ 45) is soldered onto your mother board with fine copper lines running from the individual pins of the soldered component. The fine copper lines are called traces, so if you trace the trace you should be able to follow it back to the NIC if the NIC is integrated. If you have an expansion card for your NIC well then... it's on there.
Where is the license key on dell inspiron 1545?
It's on a sticker on the outside of the case, or in the original manuals that came with the computer. If you are missing your sticker or need a way to recover your Software keys, email me @ Xeroliphe@hotmail.com
How much power can usb supply?
A standard USB port (non 3.0) can provide up to 500mAh of power. This is on full power mode.
A 3.0 port can, if plugged into a 3.0 device, provide up to 900mAh if configured to do so.
What is the expansion bus crystal?
It controls the part of the external data bus connected to the expansion slots.
Can you buy a front panel for a homemade computer case or do i have to rip one out of and old case?
You can go to your local computer and network builder and see what he has in stock and try to match it to your bays. Trying to get a bespoke one is going to be prohibitively expensive. Ripping one off an old case might well be your only option.
The physical devices that a computer is made of are referred to as?
The physical parts of a computer are all called hardware. That is opposed to ideas and invisible code called software that are encoded on a physical medium. Even a diskette or CD is technically considered hardware, while the data which is stored on it is software.
A monitor is an example of hardware?
A monitor is not normally considered hardware, the internal components of a computer are considered hardware.
